Stayed the gay hostel in Berlin. (Actually there's two - one for younger guys, the other takes all ages. I've stayed in both.)
Gay hostel: The bunks were arranged in an "L" shape along two walls. I was in the top bunk, and I could see the guy in the top bunk across from me, end-on, with some lockers between us.
Early in the morning, the other two guys got up and left, and the guy I could see on the top bunk, I guess he didn't see me because I was fairly covered up, with the lockers hiding me a bit, meaning he thought he was on his own. He knelt up on the edge of his bunk and had a good long wank, groaning and really enjoying it, with me quietly watching and by now very hard! Eventually he shoots his load on to the floor below. Some time later he climbs down from the bunk, cleans up his cum from the floor and gets dressed and ready to leave. I was so fucking hard, gently wanking under the cover.
When he passes me on the way out of the room, he spots me in the bed, first seems surprised, smiled at me as he notices me wanking and leaves. I didn't see him again.
The next day there was a new guy in the bed across me. I woke up to see he was naked and on top of the bed. I started to wank with a little bit of the covers back, so if he looked over he might see. After a while he did see, and so I pulled back the covers so he could see more of me. He got hard and started to wank too. Eventually I decided to do what the guy had done the previous morning and kneel up on my bunk and do a little show for him. I was so horny I came pretty quickly and then watched him shoot on his chest. Very hot.
In the other place I'm now apparently too old to stay at, nothing much happened in the time I was there - the guys all seemed a little shy, the communal showers had potential, but most guys used the private shower at the other end of the hallway.
Last morning there, I had a top bunk and climbed down in just my undies and stood by the bunk while sorting stuff out on my bed. The guy in the bottom bunk under wasn't there when I'd gone to bed. My morning wood was poking out a bit from the waistband of my undies, so while I'm standing there, I hear movement from the bunk below mine, I feel my undies being pulled down a bit, freeing up my cock. A mouth starts gently sucking, then a hand works the rest of my shaft. Fairly soon he gets what he wants from my cock. No words are said. Then It's my time to leave and get the train... This is indeed a very pleasant way to start the day...
